What Sumax Makes

Sumax builds ignition and electrical components for Harley-Davidson: spark plug wire sets in a range of colors and finishes, along with related ignition wiring and anodized billet accessories. What we list from Sumax moves as the catalog moves.

Fitment

Sumax fitment is specified part by part, and coverage is not uniform across platforms or model years. Check that the fitment list on the product page names your model and year before ordering.

Before You Order

Harley's electrical architecture changed several times. Carbureted points-and-coil bikes, early Delphi injection and later Can Bus systems all behave differently, and a part for one will not simply drop into another. If you are chasing a charging fault, test the stator, regulator and battery as a system before replacing parts: a bad battery will destroy a new regulator, and a failing stator will kill a new battery.
